I assume you have the PT switch on for a reason...what other directives are modifying the URL?

"/image-servlet" is an "Alias" mapped to mod_jk handler. If I remove PT directive, the request don't responds.

Hmm...I don't have any experience with mod_jk. From what I can tell, what you've posted is correct, and I verified the regex works, so my guess is that the problem lies somewhere else than in what you have here (it is just a guess though.)

Try removing QSA from your flags; in your example you are not presented with an initial query string -- QSA and a ? in the substitution will combine them, which isn't what your pattern dictates; it may be what's screwing things up. The use of NE is not warranted either given your pattern input, but it shouldn't be causing a problem. You really only need [PT,T=image/$3] I think.
